AQA Biology

What is the course about?

At Campion we offer AS/A2 AQA Biology. The exam board we have chosen is highly regarded by universities and been used by the school to teach A-Level Biology for many years. In the past few years we have had students studying Biology at Campion Sixth form who have gone on to apply/study for degrees in medicine.


AS and first year of A-level topics

1. Biological molecules – This unit looks at the few groups of carbon based compounds that interact in similar ways inside the cells of all living organisms.

2. Cells - All life on Earth exists as cells. These have basic features in common. Differences between cells are due to the addition of extra features. This provides indirect evidence for evolution. This topic covers cell structure, function and cell recognition and the immune system.

3. Organisms exchange substances with their environment – This topic examines the interchange of substances across cell plasma membranes between the external environment and the internal environment of a cell.

4. Genetic information, variation and relationships between organisms – This topic covers the details of protein synthesis, reasons for genetic diversity within a species and measurement of variation and biodiversity.


Second year of A-level topics

5. Energy transfers in and between organisms - Life depends on continuous transfers of energy, this topic covers the two main biological reactions linked to energy; photosynthesis and respiration.

6. Organisms respond to changes in their internal and external environments – This topic covers both the nervous and endocrine systems within mammals and hormone-like growth substances in plants.

7. Genetics, populations, evolution and ecosystems - The theory of evolution underpins modern Biology. This topic covers allele frequency within populations and inheritance, evolution and ancestry and speciation.

8. The control of gene expression - Cells are able to control their metabolic activities by regulating the transcription and translation of their genome. Although the cells within an organism carry the same genetic code, they translate only part of it. In multicellular organisms, this control of translation enables cells to have specialised functions, forming tissues and organs and it is this control which this topic examines.
